How are using graphs, equations, and tables similar when distinguishing between proportional and non-proportional situations?

We can determine the differences between proportional and non-proportional situations or relationships. We all need to know that linear relationships can be represented as  tables, words, equation and graphs. Non-proportional relationship will affect the y-intercept in the graph and it will no longer than zero and the ratios in the table will not be proportional.
